"Why?" - This is probably a question you ask yourself when you see this project. Who wants to watch a video in the terminal?
Well, sometimes I do. Nice for testing stuff on remote VPS without having to pull them locally. Now also supports printing jpeg, bmp, and png images to the terminal.
Turns out it's not too hard to draw a picture inside the terminal. The unicode "half block" character (▀) is a basically pixel, so when combined with ANSI escape codes, it is possible to individually colourize each one. A video is just a series of images played one after another very fast in order to achieve a sense of movement. We use FFmpeg to make a directory of images that are later on iterated through and displayed. To increase display performance, 2 text windows alternate in visibility, which greatly reduces screen tearing from the text printing across them.
Now with audio support! (I'm not sure if this is the best way to do it, but it works for now)
-dl string
Download a video from YouTube (Video ID)
-file string
File to render
-scale int
Scale of the image (default 7)
Examples:
./why -file <video> -scale <optional:default 7>
./why <video>
Scaling defaults to 1/7. The number supplied in the command becomes the denominator, e.g. 10 is 1/10.
